A survey was carried out to find out the hobbies of students in a school. The report is represented in a pie chart given below.

Calculate the percentage of students whose hobby is watching movies.

The cost of turfing a rectangular field at $50$ paise per square meter is $₹575$. If the perimeter of the field if its sides are in the ratio $7:4$ is $k \mathrm{cm}$ (correct up to the nearest whole number), then find the value of $k$.

A number consists of two digits whose sum is $13$. If $27$ is added to the number, its digits are reversed. Find the number.

Construct a quadrilateral $ABCD$, where $AB=6\mathrm{cm}, BC=3\mathrm{cm}, \mathrm{AD}=5\mathrm{cm}, \angle \mathrm{A}=65°$ and $\angle \mathrm{B}=80°$

$3.2, 2.5, 2.9, 4.1, 3.2, 2.4, 3.4, 4.2, 3.6, 4.5$

If the highest weight is $x \mathrm{kg}$, then what is the value of $x$?

The weight of newborn babies (in $\mathrm{kg}$) in a hospital on a particular day are given as $3.2, 2.5, 2.9, 4.1, 3.2, 2.4, 3.4, 4.2, 3.6, 4.5$. If the lowest weight is $p \mathrm{kg}$, then find $p$.

The weight of newborn babies (in $\mathrm{kg}$) in a hospital on a particular day are given as $3.2, 2.5, 2.9, 4.1, 3.2, 2.4, 3.4, 4.2, 3.6, 4.5$. Rearrange the weights in ascending order.

The weight of newborn babies (in $\mathrm{kg}$) in a hospital on a particular day are given as $3.2, 2.5, 2.9, 4.1, 3.2, 2.4, 3.4, 4.2, 3.6, 4.5$. Determine the range.
